Working principle
Positive Pressure Ventilation
• Introduce fresh air to generate positive pressure, continuously provide fresh air to the room. Users can enjoy the fresh air without opening the window, and ensure the oxygen content and freshness of the indoor air.
Preheating
• After it connects to air to water heat pump or boiler to preheat outdoor inlet fresh air. Improving the comfort of fresh indoor air in winter
Our fresh air ventilation system can be connected to the boiler or air to water heat pump system to achieve the role of pre-cooling and preheating outdoor inlet fresh air.
Internal Circulation Mode
• Primarily designed for extreme low-temperature environments, this mode intelligently switches between fresh air mode and internal circulation operation logic based on indoor temperature. While ensuring basic indoor air circulation, it significantly reduces heat loss caused by drawing in frigid outdoor air in such harsh conditions, thereby minimizing the overall energy consumption of both indoor heating systems and the unit itself.
Intelligent antifreeze
• When the outdoor temperature is lower than the set value, it automatically switches to smart mode, automatically switching between internal circulation and fresh air mode.
Energy saving
| Our unit | Other model | |
| Airflow-m³/h | 350 | 350 |
| Power-W | 100 | 120 |
| PTC heating-W | 0 | 2000 |
| Annual electricity consumption(KW•H) | 400 | 3300 |
Assuming it's open for half the year.The electric auxiliary heater is on for one-third of the time.
By designing a program to intelligently switch air valves, thousands of kilowatt-hours of electricity can be saved annually.
Brushless DC motor
• High efficiency: The rotor of the brushless DC motor is made of permanent magnet material, which has high efficiency and reduces energy loss.
• Great speed regulation performance: Brushless DC motors can achieve stepless speed regulation through electronic commutators, with a wide speed regulation range and strong overload capacity.
•DC silent fan, large fan, low speed, while ensuring sufficient air volume and static pressure, the fan noise is greatly reduced.
The supply air path is equipped with G4 and H12 filters, which have a dual filtering effect and effectively intercept particles and pollutants in the air. The return air path is equipped with a primary filter that can be cleaned to keep indoor air fresh.
Internal Circulation Mode

While ensuring basic indoor air circulation, it significantly reduces heat loss caused by drawing in frigid outdoor air in such harsh conditions, thereby minimizing the overall energy consumption of both indoor heating systems and the unit itself.
